Frequently Asked Questions
The “right” extinguisher depends on the specific fire risks in your London property:
Type Color Label Best For… Do NOT Use On…
Water Red Wood, paper, textiles (Class A) Electrical or Flammable Liquid fires
Foam (AFFF) Cream Wood, paper, and Flammable Liquids Kitchen fat fires
CO2 Black Electrical fires, server rooms Confined spaces without ventilation
Dry Powder Blue Multi-purpose (A, B, C & Electrical) Indoor office areas (impairs vision/breathing)
Wet Chemical Yellow Cooking oils and fats (Class F) Anything
As a general rule under BS 5306-8, you should have a minimum of two Class A extinguishers per floor, providing a combined rating of at least 26A. For London offices, this usually means a pair consisting of a 6L Foam and a 2kg CO2.
Extinguishers should be located on escape routes, near exit doors, or close to specific “high-risk” areas (like a server room or kitchen). They must be mounted on brackets or stands—never left loose on the floor where they can be used as doorstops!
Yes. Under the Regulatory Reform (Fire Safety) Order 2005, fire extinguishers must be maintained by a “competent person” at least once a year. Certivest London provides full maintenance that includes checking pressure gauges, seals, hoses, and the weight of the unit.
Even if you buy a brand-new extinguisher online, it is not “legal” until it has been commissioned on-site by a technician. This ensures it wasn’t damaged during transit and is installed correctly for your specific building layout.
Every 5 Years: Most extinguishers (Water, Foam, Powder) require an Extended Service, which involves a test discharge and a refill.
Every 10 Years: CO2 extinguishers must be sent for hydraulic testing and “overhauled” (often it is more cost-effective to replace them).
Yes. Every extinguisher must have a corresponding “ID Sign” (e.g., a “CO2 Identification Sign”) that explains what types of fires it can and cannot be used for. Our Certivest engineers check for these during every visit.
Current 2026 guidelines recommend avoiding Dry Powder indoors unless absolutely necessary (like in a garage or boiler room). The powder creates a cloud that drops visibility to zero and can cause respiratory distress, making it dangerous for office evacuations.
Check your extinguishers monthly! Look for the yellow safety pin—if it’s missing or the seal is broken, your extinguisher might have been used and may not work when you need it.
